Abstract
Abstract A security starting system for a motor vehicle is disclosed. The system includes a portable hand-held transmitting device carried in the passenger compartment of the vehicle; by the operator and a receiving device located in the housing of the starter in the engine compartment of the vehicle. An operator desiring to start the vehicle actuates the transmitter. When the receiver detects the transmitted signal, it produces an electrical signal which closes a switch connected in series to the motor vehicle ignition system thereby allowing the ignition switch of the ignition system to start the vehicle.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
180 words
A security starting system for a motor vehicle having a passenger compartment with an ignition switch therein and an engine compartment with an engine including a starter motor housing for protectively enclosing a starter motor controlled by a relay as part of a starter circuit for starting the engine of the motor vehicle, said security starting system comprising: transmitting means operative to transmit an electromagnetic signal in response to actuation thereof; receiving means operative to receive said electromagnetic signal transmitted by the transmitting means and to produce an electrical signal during times in which the receiving means receives the electromagnetic signal; and including a timer in said starter motor housing and an antenna connected to said receiving means in said starter motor housing and extending remotely to said starter motor housing for delivering the electromagnetic signal transmitted by said transmitting means; and switch means responsive to said electrical signal for controlling a period of time when said relay may be energized for operating said starter motor to start the engine of the motor vehicle by closing of the ignition switch.
Claim 2
Dependent Claim
180 words
A security starting system for a motor vehicle having a passenger compartment with an ignition switch therein and an engine compartment with an engine including a starter motor housing for protectively enclosing a starter motor controlled by a relay as part of a starter circuit for starting the engine of the motor vehicle, said security starting system comprising: transmitting means operative to transmit an electromagnetic signal in response to actuation thereof; receiving means operative to receive said electromagnetic signal transmitted by the transmitting means and to produce an electrical signal during times in which the receiving means receives the electromagnetic signal; and including a timer in said starter motor housing and an antenna connected to said receiving means in said starter motor housing and extending remotely to said starter motor housing for delivering the electromagnetic signal transmitted by said transmitting means; and switch means responsive to said electrical signal for controlling a period of time when said relay may be energized for operating said starter motor to start the engine of the motor vehicle by closing of the ignition switch.
Claim 3
Dependent Claim
15 words
The starting system of claim 1 wherein the transmitting means comprises a driver hand-held transmitter.
Claim 4
Dependent Claim
34 words
